Argentum challenges claims 13 of Novartis's U.S. Patent No. 9,006,224, which the Orange Book states will expire in 2028. The PTO concluded that Argentum has established a 'reasonable likelihood that [Argentum] would prevail with respect to claims 1-3' of the patent. The decision marks the beginning of an IPR trial that will be conducted by three specialist patent judges within the PTO's Patent Trial & Appeal Board. A final decision on patentability in the IPR is due within 1 year.
